| 摘 要： | 提出一个应用椭圆曲线密码体制进行密钥协商而在基于身份的公钥密码系统内进行组通信的全新安全组播方案，分析子组成员的密钥协商和子组间的通信过程，以及组成员动态变化时密钥的更新过程。结果表明，该方案在降低计算和通信代价方面可取得较好的效果，且满足密钥协商的安全要求。

| Abstract: | This paper proposes a novel secure multicast scheme with key agreement based on Elliptic Curve Cryptosystem(ECC) and group communication used Identity-based Public Key Cryptography(ID-PKC). The procedures of key agreement of a subgroup and secret communications between subgroups and updating of group keys with the dynamic change of group members are analyzed. Analysis result shows that the scheme is not only efficient in computation and communication, but also satisfies the security requirements of key agreement. |
